"No Video with supported format and MIME type found" in Firefox but same video plays fine on Chrome
Title is pretty self explanatory. Both browsers did not have any extensions and I'm using default settings as well.

In order to be able to effectively help you, we need you to provide clear information to show what the problem is. The exact details needed vary per case, but here is a list of things to consider:
- Your docker-compose.yml and .env files.
- Logs from all the containers and their status (see above).
- All the troubleshooting steps you've tried so far.
- Any recent changes you've made to Immich or your system.
- Details about your system (both software/OS and hardware).

and df -h
).
- The version of the Immich server, mobile app, and other relevant pieces.
- Any other information that you think might be relevant.
Please paste files and logs with proper code formatting, and especially avoid blurry screenshots.
Without the right information we can't work out what the problem is. Help us help you ;)
If this ticket can be closed you can use the /close
command, and re-open it later if needed.Firefox probably can't play the codec. What's the format? Ff is notoriously bad with hevc
yea its hevc

By default we transcode hevc to x264, so i suspect you have changed some settings
my settings seem right. i suppose the video just hasnt transcoded for whatever reason. let me try that rn

i trasncoded it and refreshed my browser but it still doesnt wanna play
eh screw it ill just use chrome to view my vault from now on
and my pixel can play the videos flawlessly too
but ty for the help!!
I've run into this same problem myself many times. Glad I finally found the answer.
I don't recall having changed any settings about transcoding, but I'll take a look. Thanks!
I have this message for every video I open in firefox, I had the settings on default when the transcoding was complete. They do work on my iphone through the immich app, and they also work on Chrome on desktop like others have reported. Is there anything I can check to make it work with firefox? I can post my settings if needed, but again I changed them once the transcoding finished and I saw it wasnt working on FF on desktop.
It should have transcoded the videos. PCM audio is passed through and not transcoded by default, so that might be why they can’t play on firefox
You can check with ffprobe
@mertalev thank you.
I want to leave a comment which will help the next person who searches this, but I cant. I restarted docker and my computer a few times. I went back into the jobs and saw that there were suddenly 9,000 jobs again. Which was confusing. I reset the transcoding settings back to default, by using the reset to default link and saved. Then shortly after I noticed some of the videos were viewable via firefox, and once the job was at 0, all my videos now are viewable
Im sure that doesnt help much, but safe to say the apps transcoding works. Why it didnt work the first time it ran, is beyond me. Maybe it never ran?
